SAN FRANCISCO (Reuters) - Members of the Screen Actors' Guild overwhelmingly approved a new contract covering their work in video games, the union's Web site said on Friday.

The vote was approved by a margin of 81.2 percent to 18.8 percent late on Thursday and sent a strong message to SAG's national executive committee, which in June narrowly voted to nullify a previous SAG member vote approving the agreement.

The contract with video game companies, including industry giant Electronic Arts Inc., was jointly negotiated by SAG and the American Federation of Television and Radio Artists.
